The convenience of parties wearing spectacles is much improved by having glasses adapted to reading and writing, to ordinary use and in walking about, and often by the use of colored glass when in strong lights. Heretofore it has been usual to carry or providetwo or three pairs of glasses, adapted to the various conveniences of the wearer. To obviate this trouble spring frames have been used into which the glasses could be pressed or taken out therefrom; these however are liable to have'the glasses accidentally knocked or shaken out on account of the shallowness of the groove I provided in the frames, which groove can not be formed deep on account of the small amount of spring provided in theframe.
